Sen. Bernie Sanders says Maine U.S. Senate candidate Graham Platner should step aside after a sexual assault allegation. Democrats across the U.S. are withdrawing support from Platner after the allegation, which Platner denies. Platner is considering his next steps and has canceled town hall events this week. The allegation involves a woman who claims Platner assaulted her in 2021. Pressure is mounting for Platner to withdraw, as Maine law has tight deadlines for replacing candidates. Democrats are divided on who should replace Platner. Platner's supporters say they're devastated and waiting for his next statement. Sanders is a Vermont independent who caucuses with Democrats and a longtime Platner supporter.
